Ed, There are some problems with the ACES, most of which are the all-too-common software errors that can be worked around. One can certainly argue that there are problems with the general testing scheme and it's validity, but I still believe that it gives you the best "artificial" performance profile that you can get. It's certainly no worse than the (obsoloscent) PIWG set, and arguably far better. (I note that your return address specifies "rivendell". In the same context, my laptop is named "Galadriel".) Phil
